eclipse - How to create a custom toggle button with an image on it that also scales correctly for each density in android -

-

Here's what I'm trying to do:

  • Create a toggle button.
  • The background color of the toggle button when one stops, then there will be a color.
  • The toggle button should have an image focus which is centered on everything.
  • The toggle button may be in 3 states, on, off, on, on, running, in which each case has more sensitivity for example and I can show how something in the button
  • I have been dialed for MDPI at exactly the button dimension diode and it is scaled for all the other density.
  • I want that the image be focused to stretch the image using the appropriate density image of the center.

    What would be the most obvious approach to all this, at least what would be the most favorable for the number of headaches and equipment? Is the whole button making background an image best? For a state and for each one density, using a button for shutting down and overlaying the image, there should be a better way on it and control the background color property for the on / off states? Probably making an XML in the "Drawable" folder is an option.

    Even one of the two states to handle the click-through toggle button The onClick method is required, for this reason I will argue that it is not more complex to create a regular button that handles the visibility of toggling in its own on-one click method.

    Since you want the option of using pictures I will use an image button for example.

    XML for an image button with custom color: 

      & lt; ImageButton android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: id = "@ + ID / toggle button" Android: layout_marginTop = "152dp" Android: layout_centerHorizontal = "true" Android: src = "@drawable / state 0 "Android: onClick =" onToggleClick "Android: background =" @color / red "/>   
     The color properties should be defined in a new XML value file (see)  
     The onClick method looks like this in the example to reverse the view of the button. Created for yourself:  
      ontoggleClick on Public Zero (see View) {toggleState = (toggleState + 1)% 3; Switch (togglestate) {Case 0: Toggle ButtonSenset Image Resource (ArduoAvate.Astate); ToggleButton.setBackgroundColor (0xffff0000); break; Case 1: Toggle. Settlement Resources (Arduvel.State1); ToggleButton.setBackgroundColor (0xff00ffff); break; Case 2: Toggle. Settlement Resources (ArduWable.State 2); ToggleButton.setBackgroundColor (0xffff00ff); break; }}   
     Please do not harsh the colors as hex values ​​in your final project, create variables for them.  
     For reference, hex color is in the form of 0xAARRGGBB  
     For Comment:  
     If you want to add text and an image to the same button Android, It supports a button that will have an icon on the left side of a button:  
      & lt; Android: layout_width = "wrap_content" Android: layout_height = "wrap_content" android: text = "@ string / button_text" Android: drawableLeft = "@drawable / button_corean" ... /> Source: http://developer.android.com/guide/topics/ui/controls/button.html   
     But then you will not be able to switch the image with the method ImageButton class

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
